By: Jonathan Bowen

Overview of this book

Talend Open Studio for Data Integration (TOS) is an open source graphical development environment for creating custom integrations between systems. It comes with over 600 pre-built connectors that make it quick and easy to connect databases, transform files, load data, move, copy and rename files and connect individual components in order to define complex integration processes. "Getting Started with Talend Open Studio for Data Integration" illustrates common uses and scenarios in a simple, practical manner and, building on knowledge as the book progresses, works towards more complex integration solutions. TOS is a code generator and so does a lot of the "heavy lifting"ù for you. As such, it is a suitable tool for experienced developers and non-developers alike. You'll start by learning how to construct some common integrations tasks ñ transforming files and extracting data from a database, for example. These building blocks form a "toolkit"ù of techniques that you will learn how to apply in many different situations. By the end of the book, once complex integrations will appear easy and you will be your organization's integration expert! Best of all, TOS makes integrating systems fun!

Advanced XML output for complex XML structures

The XML output format we used in the last example was pretty straightforward. Every piece of data is contained within its own XML element; however, it is very common for XML files to be more complex, with subelements being repeated within a parent element, and data items being held in XML attributes rather than in elements.

In this example, we will produce an XML file that contains data about customer orders that have been dispatched. This file will contain the following information:

  • The order ID

  • The order-line ID

  • The product SKU for each line

  • The quantity of each dispatched SKU

  • The dispatch date (in the format yyyy-MM-dd hh:mm)

  • The courier tracking ID (so that customers can track their order)

The XML format we need to adhere to is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<ORDER ID="1000">
<ORDER_LINE ID="1" SKU="123456789" QUANTITY="1" DISPATCHED_DATE="2011-01-01 12:00" TRACKING_ID="ABC12345"/>
